Mouse invisible after upgrading to Radeon RX 7900 XTX

After upgrading my graphics card to a Radeon RX 7900 XTX the mouse is invisible under X11 session on the KDE version of Manjaro. This bug is also present using a bootable USB of the same version. So, it is independent of my current install. The bug is also present on a clean install of the OS (which is not easy to do with an invisible mouse). The only solution I have found is:

sudo pacman -R xf86-video-amdgpu

After removing that driver the mouse does work and is visible again.

I also had this problem. You need to enable a software rendered cursor.

One way to do this is to add a custom Xorg configuration file in /etc/X11/xorg.conf.d/ and in the section “device” add the “SWcursor” option. That part of the file I made looks like this:

Section "Device"
    Identifier     "Device0"
    Option         "SWcursor"  "True"
    Driver         "amdgpu"
    VendorName     "AMD Corporation"
    BoardName      "AMD RX 7900 XT"
EndSection
